Support for copying Zotero Select URL

Hi, thanks for this great tool!
One of my main use cases for Zotero is linking from other note-taking tools, especially from Markdown - like `[citekey](zotero://select/{etc})`. I was wondering what a convenient way to use Zothero to copy the Zotero select URL to the keyboard (or, even better, the full link style I wrote above) might look like. It would be ideal to set this as a 'citation style' of its own.

It seems like it might be pretty straightforward, since said URL is already used for the `open-in-zotero` action. By adding a 'Copy to Clipboard' action that copies `{var:url}` to one of the existing actions, I can get the URL copied, but this is hacky - I'm just not sure how to do it better.
